PILE-WIRE CUTTER.

` Application filed June Z5, 1928.y Serial No. 118,401.

My present invent-ion relates to pile Wires,

and has particular reference tothe bla-deholder which is associatedtherewith.

The use of pile wire cutters in the manufacture of pile fabrics'is besetwith many dif- `ficulties. @ne of these has its origin in the necessityfor constantly replenishing the For this purpose, it is customary toprovide the blades in the form of flexible wafers, and to provide theblade holders with siutable means for properly positioning the bladesand at the same time permitting ready removal thereof.

Another one of the difficulties encountered in the use of pile wires isbased upon the different requirementsl of different looms or mills. Moreparticularly, in certain cases a pile wire of a certain height or havinga blade receiving channel of a certain depth, is used or required, andin other cases, pile wires having a dierent height or channel depth arenecessary. It has therefore been necessary heretofore to provide bladeholders, either as attachments for the pile wires or as integral partsthereof, in varying sizes; and more particularly,`ithas been necessaryto provide blade holders of different heights. Inasmuch as the cuttingblade must project out of the blade holder by a proper predeterminedamount, it has been necessary to provide not only holders of differentheights, but also blades of different sizes. The reason for thiswill beobvious. Where blade holders are used which comprise U-shaped channelsformed'by doubling over a substantially flat blank, an increase in theheight of the blade holder will produce an increase in the depth ,of thechannel. As ,a result, a blade having a affecting great economies in themanufactureof blade holders.V

In accordance with the embodiment herein is capable'of being associatedwith the blade holder so as to reduce the edective depth of the channeltherein. More particularly, I provide a series of these plugs, the plugsvarymg in size in accordance withv the varying heights or channel depthsof blade holders, so that anyselected blade holder may be standardizedvby the association therewith of a properly selected insert.

For the attainment ofthe foregoing objects and such other objects as mayhereinafter' appear or be pointed out, I have illustrated my inventionin the accompanyingdrawings in which:

Fig. 1 is a side elevation of a pile wire blade holder of relativelysmall height, having associated therewith a blade which may, A

foie"l illustrative purposes, be considered standar v Fig. 2 is asimilar view of the blade unassociated with my holder;

Fig. 3 is a perspective viewof a blade holder having a relativelygreater height, fand having the standard blade associated Vtherewith inaccordance with the present invention;

Fig. 5 is a view'similar to Fig. 3 of fication.

a modi- As to the structure of Figs'. 1 to 4, this apv plication is acontinuation of my earlier filed application No. 107,334. c l

Referring to the drawings, it will be observed that I have shown a bladeholder 10 of a substantially fiat blank doubled-overv along alongitudinal line 12 to form a U- shaped blade receiving channel 13./f'hile I specilically illustrate and describe .herein a pile wire bladeholder formed by bending a vblank intermediate its ends to provide achannel within which the blade. is received, itwill be understood thatthis is done for purposes of illustration and this channel might'beformed by reaming out or otherwise removing a portion of the mateterialof a solid bar vfrom which the` holder is to be'formed. c rIhe bladewhich I prefer to use isof ,the

liexible'wafer type having a bottom edge"A 14, disclosed, Ipr'ovide aninsert or plug which a cutting edge y15 disposed'at'an angle tothe Aedge 14, and aforward edge 16 which coinpletes a generallytriangularligure. The

.blade is associated with a holder by positioning itsrear end, or foot17, under an overhanging wall of the characterherein-y before referredto. The other end 1S is constructedin a' inanner which permitsoo-operation thereof with a .suitable tab 1 8 provided en the spoon.portion 11. More par-l ticularly, this tab 18 is struck up out of thespoon portionv 11 inte the path of the channel,rand it comprises aforward edge 19, and upper and lower edges and 21 respectively, each 'ofthe edges 19,20 and 21having been formed by cutting proper slits throughthe spoon por 4V'on 11. For a purpose presently to beunderstood, `theslit 20 iapreferably made shorter than the slit For properl eooperationwith the tab 18, the. endlrof the blade is constructed with a. cut-outportion which 'provides an endedge 22 parallel. to the edge/16 butoffset with respect thereto, and a connecting edge 23 substantially par-Aall'el to the edge lll. VAft-er the foot'lr.7 of

theblade has been properly positioned, the

entire blade is flexed so that the end 16 will spring into place beneaththe tab l18. More particularly, the edge 23 will be caught by the end ofthe slit 20, while the edge 23 will encounter the edge 21 and 'preventyupward nxoi'fement of the blade after it has been po- Sitioncd. f 'Y yY I `sihall now 'describe the construct-ion Awhich permits engagement ofthe foot 17 of the blade. The general purpose isto provide anoverhanging wa'll'21l V(Fig. 1) beneath which the foot 17 mayrest. Thisoverhanging wall assumes a general direction extending from the rearbase of the channel up Wa-'rdly and forwardly to Ythe open end of thechannel. In Fig. 8 Ihave shown one method of achieving this result. Iprovide a wedge-shaped insert25 having an under ,edge `2b which may besaid toV` be beveled.

. More specifically, the 'under-edge 26 is arranged Vat an angle to theaxis 'of @the channel.' Thereby, only :a portion of theohan-nel iseectively b'locke'dby thewedge .25. This portion is'the outer portion ofthe channel,

the inner portion-being unblocked by the insert and constituting van`luidereut recess.V

Theme1nber'25 may be secured in position Y by any suitable means, as bywelding, or

soldering or otherwise. YVlhere a ineniber this type isused, 'I preferto shape yits outer edge' in la inanner which will :make it .conform Vtothe upper kodge =of lthe *blade holder. The inclination vof theunder-edge "26 optional, as may be 'well understood.

"It will be understood'ithatfby properly positioning the wall 22 of theblade with ref- 'erenee to the'edgc `19fofthetab 1:8, that theVblade/can beinserted'by-a fulcruming action 'of its .end '17 Saboutfthe uppernp'ginted/fend of the insert 25 so as to permit of the por-Leeebee tion of the blade defined by1` the reference characters 17 and28 inFig. 2,v to der over 22 of the blade so as to have the edges 20..

l 22"pes1tioned adjacent each other but not in overlapping position,nient can as already explained, ng new to Fig. S, I 'have shown astandardized blade associated with a blade holder having a heightIgreater.than that of the blade holder` of Fig. l. "lhis blade holdercomprises a similar .spoon portion 11, tab 18', and channel portion13'.. It will @be 0l ser-ved, however, that the. depth of the ohannelis, in this case, inuch .greater than `that of Fig.` 1. Infact, thedepth .of the channel This Veinb odiis too great, with respect to .theblade depth,

to permit proper positioning of the blade witlnntheehannel, so as `tohave the properV amount of projection out of the channel.V

For rthe purpose of rendering this. blade Iholder available-for use withthe standardized blade, I provide a ,plugging member 33 in vthe fornivofa str-ip, this ineni'ber being insertable into .the channel 13 so asto provide a raised bottom therefor, Bythe proper selection of insert33, the new bott-om may be ,provided at a :predetermined 4raised pointwith respect ,to the bottoni of the helder.V The blade maybe made to.rest upon this lsubstitute ybottom in lieuof .the original channelbottoni. The vinsert 33 may be suitably positioned by soldering,welding, or .merely by frictional engagement withinthe channel, It willbeun-derstood that' its application need not necessarily affect ltheioverhanging wall construction hereinabove described. The

latter may be provided :upon the basis of the newly formed bottoni.llhat is, where a wedge member is .cinployed,it `may be preferablyassociated withinthe cha-nnelso as to 'Xtend only-.to the insert' 33.This, however, is not essential, as will .be understood.v i

It will be obvious that `various changes in the .details hereindescribed and illustrated Yfor the purpose of explaining therature .of

be inserted by a fuleruniing action' `my, invention may be made bythosesliflled in the art withoutdepart-ing rmmthe spirit and scope ofthe invention as .ey-pressed 1th@ appended claims. It is therefore.iilllidd that Vthese details be interpreted illustrative, aesinet inalmitingfsense- Having thus described my invention and ylao - wherebythe blade may be used interchange-V ably with different holders andstill project out of the channel byy a predetermined amount. y
